Abstract
A capillary pumped loop system includes an evaporator for vaporizing a refrigerant by absorbing heat from the periphery, a condenser for turning the vaporized refrigerant into a liquid by radiating heat from the vaporized refrigerant, a tube for forming a circulatory path connecting the evaporator to the condenser, and a capillary unit installed to form a plurality of gaps within the tube so that the refrigerant can move along the circulatory path due to capillary action caused by the gaps. Accordingly, when the refrigerant passes through the capillary unit due to the capillary action, bubbles in the tube can be reduced. In addition, a multi-path is formed for the movement of the liquid refrigerant, so discontinuation of the refrigerant can be prevented, thereby preventing the refrigerant in the evaporator from drying out.
